Application filed April 25, 1911. Serial No. 6235.36.

To aZZ whom fit' may concern:

Be it known that l, ARTI-inn R. Havanna,

a citizen of the United States, residing at lWaltham, inthe county ofMiddlesex and State of lvlassachusetts, have invented new and usefulimprovements i'n Machines for Setting Rivets, of which the following isa speciiication.

This invention relates to a machine for setting rivets in sheetmaterial, the machine being particularly adapted to set rivets in tiresfor automobiles.

The object of the invention is to provide a machine of the character setforth which is adapted to set rivets in automobile tires and hold thematerial in which the rivets are set in curvilinear forni in crosssection during the setting of said rivets, as distinguished frommachines in which the rivets are set in the sheet material oi which thetire is formed while said sheet material is iiat and before it is bent.

The advantage gained by setting the rivets in the tireand simultaneouslyshapingthe tire into a serni-circular form in cross section is that therivets assist materially in holding the tire in said cross sectionalshape after the setting operation is completed', whereas if the rivetsare' set'in the sheet material prior to its being formed in asemicircular shape, or while the tire is fiat in cross section, it will.be much more diihcult to subsequently bend the tire into a crosssectionor' seinibircular contour.

The invent-ion consists iii the combination and arrangement of paits setforthin the following specification and particularly pointed out in theclaims thereof.

Referring to the drawings: Figure l is a front elevation of iny improvedrivet setting machine, with the work-support broken away vation of thesame, as viewed from the right of Fig. l, the work-support 'anda portionof the arm upon which it is supported be-v ing shown in section. F ig. 3is a side elevation of the machine as viewed from theleft of Fig. l, thework-support being shown in dotted lines in different positions. Fig.. lis an enlarged Jiront elevation, partly in section, of the rivet settingmechanism, and work-support with a tire in position thereon and severalrivets-set in said tire, the driver and rivet holder being shownelevated. l Fig. 5 is a view similar to Figa,

Fig. 2 is aside ele- 'ley 3l driven by a .part to the lower part tion,as shown inv Fig. 1, by a spring 39.

withL the parts in the relative positions occupied thereby ywhen therivet is being set in the tire. Fig. 6 is a sectional plan taken on line6--6, Fig. l, showing the vtire as it is placed when the rst row orseries o rivets is being set therein. Fig. I is a sectionah plan similarto Fig. 6 illustrating the tire in the position occupied. thereby whenthe' second row of rivets is being set. Fig. 8 is a detail sectionalelevation taken on line 8-8 of Fig. 7.

. Like numerals refer to like parts throughout the several views of thedrawings.

ln the drawings, 10 is the htrame of the machine supported upon a columnll. 12 is the driving shaft journaled in bearings 13, 13 on said traineand driven by a pulley 14. Said shaft l2 has a pinion l5 fast theretowhich'ineshes into a gear 16, fast to a shaft 17 journaled in bearings18, 18 on the frame of the machine. The driver 19 is fastened to adriver-bar 2O arranged to slide in ways 2l' formed in the frame of themachine and a reciprocatory motion is imparted to said driver by acrank-pin 22 fast to a cam-plate 23 which, in'turn, is fastened to theleft hand end of the shaft 17.v The crank-pin 22 is connected by a link2a to two links 25 and 26, the link 24 being connected to said links 25and 26 by a pin 27 The link 25 is pivoted at 28 to the traine of themachine. rlhe link 26 is connected by a pin 29 to the driver-bar 20.Thus, as the shaft 17 rotates,

the cranli-pin 22 moves the connecting link 24. longitudinally oisaidvlink (Fig. 3) and through the links 25 and 2G a reciprocatorymotion is imparted to the driver-bar 20.

The rivets are place-fl in mass in a hopper 3() having a rotary feedwheel or separator therein (not shown in the4 drawings) to which arotary motion is imparted by a pulcross-belt 32 Jfrom a pul ley 33 fastto the gear l. The rivets are fed from the hopper in a 'manner wellknown to those skilled in4 this art onto a raceway 34 down which theypass to la separator 35 which feeds them one by one freni-the upper ofthe raceway, and

from the lower part 36 of the raceway theyl pass into the rivet holder37, into which they drop one by one as illustrated ii'i'Fig.A

4. The holder lower end of a slide 38 arranged to slide iii ways andheld normally in its elevated posi-- 37 is supported upon` the i t Fig.l) to theframe of the machine.

free end of the feed finger 60 is held with stop-pin 40 is fastened tothe holder slide 3S and projects into a slot 41 in the front plate 42.Said holder 37 is made in two parts 37", 37 which are fastened tosprings 372, 372 which, in turn', are fastened to the slide 38, andthese springs yield to allow the rivet to be pushed out of the holder bythe driver when `the same descends in a manner well known to thoseskilled in this art.

A reciprocatory motion is imparted to the separator 35 by a lever 43which. is connected to said separator by a spring arm 44 and is pivotedat 45 to the frame of the Inachine. The upper endof the lever 43 (seeFig. has a roll 46 j ournaled thereon which bears against an incline 47on the link 24. A spring 48 holds the roll 46 against the inoline 47.

vThe piece of sheet material or tire 102 into which the rivets are to bedriven is supported upon a work-support 49 consisting of a centralmember or Aholder 5() and two hornshapedlmembers 5l;l 5l rotatablymounted on opposite sides, respectively, of said central member 50. Theworlcsupport, as a whole, is ccnvexly curved on 'the side 52 thereofadjacent to the driver 19 and is located beneath said driver'. Saidholder is circular in cross section, as illustrated in Fig. 8. The horns5l, 5l are :fastened to an axis 53 which extends transversely of thedriver 19 and is rotatably mounted in the central member or support 50.interposed between the horns 5l, 5l and the central member 50 of thework support are friction rings 54, 54 whichare pressed against thecentral'member 50 by springs 55, 55 located in recesses provided Ain thehorns 5l, nl. '/lhe central member 50 terminates at its lower end in ascrew-threaded shank provided with adjusting nuts 57, 57, one of whichis mounted above and the other below 'the arm 58 of the frame l0. Bymeans of -these adjusting nuts the work-support can by a feed linger .60which is pivoted at 6l toa lever 62,- said lever 62 being pivoted at 63The a yielding pressure against the, surface .of the tire which is fedthereby by means of a spring 64 and is moved from left to right and viceversa by a link 65 which is pivcted/at one end thereof to a pin 66 fastto the driver bar y,20. At its outer or free end thclink 65 is slottedat 67 and through this slot projects a pin 68 which is fastto the lever62. y

The position of the lower end of thefeed finger 60 may be regulated bymeans of the adjusting screw 69 having screw-threaded engagement'withthe link 65 and bearing at its inner end against the pin 68, whereby, byturning the screw 69 in one direction or the other7 the pin 68 may bemoved along the slot 67 and thus the lower end of the feed finger willbe moved or adjusted to the desir-ed location. .It will thits be seenthat by means of the screw 69 the length of feed or the distancewhichthe tire is moved on the work-support may be increased ordiminished.

is the driver moves down the-feed lever 62 and feed linger 60 will bemoved to.- ward the left (Fig. l) as soon as the right hand end of theslot 67 abuts againstthe.v

pin 68, and 'as the driver moves upwardly the lever 62 will be swung,together with thef feed finger 60, toward the right, thus feeding thetire along the work-support, Ait be! ing understood that the end of thefeed finger, inthe feeding operation, abuts against the rivet which hasbeen set last inxthe tireby the driver, as hereinafter more fully ez#plained.

ln order to insure accuracy offeed, a stop'- 7U` is provided which isfastened toa slideV 71, this slide being mounted in .waysv in the frameof the machine and a reciprocatory motion imparted thereto by means ofva lever 72 .pivoted at 7 3 tothe frame of the mav chine. Theilever 72 isconnected to the slide 7lA by a pin 74, and a rocking motion is'lim-lparted to the lever 72 by the cam plate 23 against ,which a frictionalroll 7 5 jmirnaled` upon the lever 72 bears. lhe lever 72ter`- minutesat its free end in a'hazadle 76'.

icel

whereby the same may be operated by hand,

it desired, to raise and lower the stop 70. A spring 77, one end ofwhich is fast to the outer end of the lever 72 and the'other end to theframe of the machine holds the roll 75 in contact with the periphery ofthe cam 23.' of contact with the work, the leverl 72 is raised by thehandle 76 and is held in an elevated position by the pin 7 S which isfastto said lever, riding up over andresting upon a stationary bevel pin79 fast to the frame of themachine. It will be noted that the lower endof the stop 7() is beveled to W'hen it is desired to hold the stop outallow the saine to project 'in betweenthe heads of two adjacent rivets,as seen in Figs.'

4 and 5.

0n the same slide 7l is supported a gage 8O and the lower end of thisgage is also beveled to project in between two adjacent 'rivets inanother row4 of rivets from that row with which the stop 7 0 is inalinernent. lt will also be noted by reference to Figs. 6 and 7 that thestop70 is in alinement with the feed ngerO while the gage' 80`is out ofalinementwith the feed linger 60 and also out of alinementjwith the stop70, being .adapted to project'in b/etween the bev- -laterally from thegage c.,

ment.

A guide 81 is fastened to and to project between twe A' rivets to guidethe saaie the being fed forward. Another guide S52 is provided which isgrooved upon its u' der side at 83 to receive and guide the rivets andthe material to which they are fastened. This guide 82 has a stern 85which projects into the lower end oi' a slide Sti and is clamped theretoby a clamp-screw 87. The slide 86 sli des in ways provided in the frameand is held downwardly against the material by a spring 88, one end ofwhich is fastened to a pin S9 on said slide and the other end of whichis fastened to a screw 90 on the frame of the machine. The guide 82 maybe moved upwardly and held in its upward position by a spring clip 91(see Figs 1 and An edge gage 92' is provided which adapted to bearagainst the edge of the niaterial when the first row of rivets is beingdriven therein, said gage having a stem 93 thereon which projectsthrough a block 9e pivoted at 95 to arms 96 which7 in turn, are pivotedto a bracket 97 fast to the frame of These arms 96 are held in the 98pivoted at 99 to the i'rarne ci the machine. When it is desired to throwthe edge gage 92 backward out of the way, it may be done by firstthrowing the arm 98 out oi the way and then tipping the arms 96 upontheir pivots toward the right (Fig. 2). rlhe stern 93 is clamped inposition in the block 94C by a clamp-screw 109 and the block wl isclamped in position upon the arms 96 by a clamp-screw 101.

The general operation of the :machine hereinbeore specifically describedis as follows: The tire is placed on the work-support i9 in the positionillustrated in F ig. 6, with the edge of the saine resting against theedge gage 92 andlthe machine operated to set the first row or rivets84;. this row of rivets the driver descends', being driven by themechanism hereinbeiiore described, carrying with it the holder 37 andthe rivet contained therein, movin@ the same from the positionillustrated in Fig. until the pin si() on the holderslide 38 arrives at.the betteln of the slot 41, at which imc the bottoin'ol' the rivetholder will be nearly in contact with the tire 192. Upon a continueddownward movementA or. the driver-oar Q9 and driver 19, the rivet beforced ont of the rivet holder through the tire 192 and will be clenchedagainst anvil 198 in the holder 50 oi the work-support e9. The holder3'? and the slide 38 move upwardly 'while the fourth row or" rivets'will rt ln setting f "s driven ont saine having the i De is' the towardt' g. i it aouts against the stop 'T0 widen. is moved, downwardly intime to be engaged by the head of seid rivet by lthe lever 72 and Thefeed linger then regreats and vhe stop T0 is raised preparatory 'to thesett" D other rivet in the tire and the feed i g of the tire by means ofthe second rivet and the leed linger, as hereinbei'ore described.

filter the first row of rivets v'. set,l the tire is reversed upon theworlrk port, bringing the irst row of rivets eut iront of the driver, asilliistrated in v. and the second row ot rivets 8st wen driven. Buring`the driving of' the second row oi rivets, the tire guided by the rivetsof the first row, passing through the groov S3 in the under side ci' theguide lt .is

also guided or placed to correct any iracd curacy ci' position by theguide and i 8G which as the slide "T51 descends top 70., also bringsdov/nwe 8O the Aguide 81, the tering between two adjacent ri. ries etrivets 84.- and placing a position that the rivets of. rivets 84; willbe staggered 7 w' ence'to the se 'ies oi rivets the re f lcation of thegage 80 and sten "50 sich that when 'the stop 'YG' is b of the rivets ofthe series Se the be in alinernent with the middle o.' said rivets ofthe series 842;. The rows or rivets will 'be driven in the saine in neras hereinbefore deseribed7 theLthird rc i oi rivet-s being staggered as'to the second5 but registering with the' rivets in the row Se,

with the rivets in the row Se and conse qnently will be staggered l? asto the rivets in the row 8e and as to the thirl row oi rivets.

lr" the tire is not in the exact position to correctly locate the rivetsof one row with respect to the adjacent row which has just been driven,the beveled end of the gage 8O will enter between the adjacent beveled.heads of the rivets in the row 8"; and will push the tire 'i correctiv lcate the L i the w i vet. l:- will ne guide 81 in descent. i g ocorrectly loca-te the row i. has :inst been driven relatively to ndriver.

lluring tile operation hereinb ore described the is around elif;

the median axial line of the shaft 53, so that the dilerent rows ofrivets Will' come beneath the driver without shitting the tire on theWork-support laterally thereof, the different positions ot' the worksupport being illustrated in dotted lines in F ig'. 3 to accomplish thisend.

It `will be seen that the presser foot guide 82 assists in shaping thetire sov that it will be or" semi-circular shape in cross sectionalcontour, particularly by reference to F ig. 8, in which the tire isshown pressed downwardly at the right of the row of rivets which isbeing set and as being bent into curvilinear shape in cross section, andthis operation of bending continuous to be per# formed by the presserfoot guide 82 as each subsequentrow of rivets is fed therebeneath, sothat tinally the tire, when the rivets have been driven therein, hasbeen formed. into a semi-circular shape with the shanks of the rivets inone row of rivets converging toward the shanks of the rivets in theadjacent rovv of rivets.
